Answer:
1 : 2 cm/km or
One cm represents 2 km.
Explanation:
If 3 cm represents 6 km on the earth, the ratio to consider is: 3 : 6 cm/km which is the same as:
1 : 2 cm/km or
One cm represents 2 km.

We have the equation of motion
, where v is the final velocity, u is the initial velocity, a is the acceleration and s is the displacement.
In this case initial velocity = 2.20 m/s, final velocity = 0 m/s, displacement = 14 m
On substitution we will get 0 =
On solving we can find the acceleration value as -0.173
So free fall acceleration = 0.173
Answer:
Explanation:
From the question we are told that
Velocity v=28m/s
Distance d=280
Generally the Newtons equation for motion is mathematically given as
Acceleration
